For anyone currently experiencing a bug where you lose all control of the player after completing a dialog sequence at upgrade terminals -- I should have a fix for you here, and the latest game update will have a fix to avoid it from happening in the first place for new users.

The issue seems to have been an error in how the game creates a settings save-file when there is not already one present, along with the way that Unreal helpfully buries that .sav file deep within the hidden AppData folder within windows that is not always removed on uninstall.

If You Have Already Experienced The Bug

• Open the OPTIONS menu (from the main menu when the game loads, or from pausing the game with start or select on the gamepad, or enter on the keyboard and choosing "OPTIONS")
• Select any controller mapping preset (Default, TYPE-A, TYPE-B, TYPE-C), even if it's the one you're already using
• Click on "Accept", updating your options save file.

And that's it. Now when you complete dialog, the game should return you to your chosen gameplay-related input map set, as intended.
